The Prophet ﷺ forbade the mixing of ripe and unripe dates and also the mixing of dates and raisins (for preparing a syrup) but the syrup of each kind of fruit should be prepared separately. ( One may have such drinks as long as it is fresh )  

نَهَى النَّبِيُّ ﷺ أَنْ يُجْمَعَ بَيْنَ التَّمْرِ وَالزَّهْوِ وَالتَّمْرِ وَالزَّبِيبِ وَلْيُنْبَذْ كُلُّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ  

"The Messenger of Allah [SAW] forbade mixing Al-Busr and raisins, and Al-Busr and dried dates, and he said: 'Soak each one of them on its own.'"  

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يُخْلَطَ الْبُسْرُ وَالزَّبِيبُ وَالْبُسْرُ وَالتَّمْرُ وَقَالَ انْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ  

‘Do not make Nabidh with dried dates and unripe dates together, make Nabidh with each of them on its own.”  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَنْبِذُوا التَّمْرَ وَالْبُسْرَ جَمِيعًا وَانْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَتِهِ  

“Do not combine fresh dates and unripe dates, or raisins and dates; rather make Nabidh with each one of them on its own.”*  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ تَجْمَعُوا بَيْنَ الرُّطَبِ وَالزَّهْوِ وَلاَ بَيْنَ الزَّبِيبِ وَالتَّمْرِ وَانْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَتِهِ  

Prepare Nabidh from each one of them separately. (Using translation from Muslim 1989a)   

نَهَى رَسُولُ اللهِ ﷺ عَنِ التَّمْرِ وَالْبُسْرِ وَالزَّبِيبِ وَالتَّمْرِ أَنْ يُنْبَذَا  

Prepare Nabidh from each one of them separately. (Using translation from Muslim 1989a)  

نَهَى رَسُولُ اللهِ ﷺ عَنِ الزَّبِيبِ وَالتَّمْرِ وَالْبُسْرِ وَالتَّمْرِ وَقَالَ يُنْبَذُ كُلُّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ  

‘Do not make Nabidh with dried dates and unripe dates together, make Nabidh with each of them on its own.” (Using translation from Ibn Mājah 3396)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَنْبِذُوا التَّمْرَ وَالزَّبِيبَ جَمِيعًا وَلَا الْبُسْرَ وَالتَّمْرَ جَمِيعًا وَانْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ»  

[Machine] I heard the Messenger of Allah ﷺ forbidding the mixture of dates, dried yogurt, and fresh dates. He said, "Drink each one separately."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَنْهَى عَنِ الْخَلِيطَيْنِ التَّمْرِ وَالْبُسْرِ وَالرُّطَبِ وَقَالَ اشْرَبُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَتِهِ  

[Machine] The Messenger of Allah ﷺ said, "Do not cast aside dates and raisins, but take each of them individually."  

قَالَ رَسُولُ اللهِ ﷺ لَا تَنْبِذُوا التَّمْرَ وَالزَّبِيبَ وَانْتَبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَتِهِ  

“Do not combine fresh dates and unripe dates, or raisins and dates; rather make Nabidh with each one of them on its own.”* (Using translation from Ibn Mājah 3397)   

عَنِ النَّبِيِّ ﷺ قَالَ «لَا تَجْمَعُوا بَيْنَ التَّمْرِ وَالزَّبِيبِ وَلَا بَيْنَ الزَّهْوِ وَالرُّطَبِ وَانْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ»  

The Prophet [SAW] forbade mixing Az-Zahuw and dried dates, and mixing Al-Busr and dried dates, and he said: "Soak each one of them on its own in vessels that are tied shut." (Using translation from Nasāʾī 5567)   

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ خَلِيطِ الزَّهْوِ وَالتَّمْرِ وَخَلِيطِ الزَّبِيبِ وَالتَّمْرِ وَقَالَ انْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ فِي الْأَسْقِيَةِ الَّتِي يُلَاثُ عَلَى أَفْوَاهِهَا  

"The Messenger of Allah [SAW] forbade mixing Al-Busr and raisins, and Al-Busr and dried dates, and he said: 'Soak each one of them on its own.'" (Using translation from Nasāʾī 5570)  

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ نَهَى رَسُولُ اللهِ ﷺ أَنْ يُخْلَطَ التَّمْرُ وَالزَّبِيبُ وَالْبُسْرُ وَالتَّمْرُ وَقَالَ انْبِذُوا كُلَّ وَاحِدٍ مِنْهُمَا عَلَى حِدَتِهِ  

"لاَ تَنْبِذُوا التَّمرَ وَالبُسْرَ جَمِيعًا، وَانْبِذُوا كُلَّ وَاحدٍ مِنهُمَا عَلى حِدَتِهِ".
